When the cleaning brush rotates to avoid, the traction rod will be driven to move, so that the first piston will move to discharge the gas inside the air pressure box into the outer cylinder through the air pipe assembly, so that the push rod is extended to support the device with the support legs. At this time, the device is in a suspended state and cannot move, so that the device area can continue to clean, avoiding the device from continuing to work during the cleaning brush operation, resulting in more and more hair entanglement, thereby causing the device to lose its cleaning effect.

[0019] 3. After the hair is removed, the cleaning brush of the present invention no longer swings, so that no air enters the outer cylinder. At this time, the elasticity of the third spring will reset the second piston, so that the device can contact the ground again to move and work. At the same time, the second one-way valve can also discharge the high-pressure gas inside the outer cylinder during operation, so as to avoid the high air pressure inside the outer cylinder affecting the swinging work of the cleaning brush, resulting in the cleaning effect of the device not working well.

[0020] 4. The contact wheel of the present invention contacts the driving wheel, so that the device can drive the collection roller to rotate during movement, thereby making it easier to collect the garbage swept into the collection box by the device, and also preventing the garbage from leaking out after a certain amount of garbage storage. The dust collection plate can collect dust separately, which allows dusty garbage to be classified and dumped when dumping garbage, avoiding dust splashing when dumping garbage.

[0029] like Figure 4 As shown, the garbage collection component 6 includes a collection box 601, a limit block 602, a baffle plate 603, a dust collection plate 604, an electrostatic plate 605, a fan 606 and a handle 607, and the limit block 602 is installed on the left side of the lower end of the collection box 601, the baffle plate 603 is installed on the right side of the collection box 601, and the dust collection plate 604 is installed in the middle of the collection box 601, the electrostatic plate 605 is installed on the upper end of the dust collection plate 604, and the fan 606 is installed on the upper end of the electrostatic plate 605, and the handle 607 is installed on the upper end of the collection box 601.

[0030] like Figure 5 and Figure 6 As shown, the transmission assembly 7 includes a collecting drum 701, a first connecting shaft 702, a transmission belt 703, a second connecting shaft 704 and a contact wheel 705, and the front and rear ends of the collecting drum 701 are connected with the first connecting shaft 702, the outside of the first connecting shaft 702 is connected with the transmission belt 703, and the lower end of the transmission belt 703 is connected with the second connecting shaft 704, and the side of the second connecting shaft 704 close to the collecting drum 701 is connected with the contact wheel 705; The contact wheel 705 of the present invention contacts the driving wheel 102, so that the device can drive the collection roller 701 to rotate during movement, thereby making it easier to collect the garbage swept into the collection box 601 by the device, and can also prevent the garbage from leaking out after a certain amount of garbage storage. The dust collection plate 604 can collect dust separately, which can classify the dust and garbage when dumping, avoiding dust splashing when dumping garbage.

[0031] like Figure 7As shown, the pneumatic assembly 8 includes a pneumatic box 801, a first one-way valve 802, a first piston 803 and a traction rod 804, and the first one-way valve 802 is installed outside the pneumatic box 801, the first piston 803 is installed inside the pneumatic box 801, and the left side of the first piston 803 is connected to the traction rod 804; When the cleaning brush 904 rotates to avoid, the traction rod 804 will be driven to move, so that the first piston 803 will move to discharge the gas inside the air pressure box 801 into the outer tube 1101 through the air pipe assembly 10, so that the push rod 1106 is extended, and the support leg 1107 supports the device. At this time, the device is in a suspended state and cannot move, so that the device area can continue to clean, avoiding the device from continuing to work during the operation of the cleaning brush 904, resulting in more and more hair entanglement, thereby causing the device to lose its cleaning effect.

[0032] like Figure 8 As shown, the air pipe assembly 10 includes an annular air pipe 1001 and a lower connecting air pipe 1002 , and the lower end of the annular air pipe 1001 is connected to the lower connecting air pipe 1002 .

[0033] like Fig. 9 As shown, the push-up assembly 11 includes an outer cylinder 1101, an exhaust hole 1102, a second one-way valve 1103, a second piston 1104, a third spring 1105, a push rod 1106 and a support leg 1107, and the exhaust hole 1102 is opened at the upper end of the outer cylinder 1101, the second one-way valve 1103 is connected to the side of the outer cylinder 1101 away from the shell assembly 1, and the second piston 1104 is installed inside the outer cylinder 1101, the lower end of the second piston 1104 is connected to the third spring 1105, and the push rod 1106 is arranged inside the third spring 1105, and the lower end of the push rod 1106 is connected to the support leg 1107; After the hair is removed, the cleaning brush 904 of the present invention no longer swings, so that no air enters the outer cylinder 1101. At this time, the elasticity of the third spring 1105 will reset the second piston 1104, so that the device can contact the ground again and move. At the same time, the second one-way valve 1103 can also discharge the high-pressure gas inside the outer cylinder 1101 during operation, so as to prevent the high air pressure inside the outer cylinder 1101 from affecting the swinging operation of the cleaning brush 904, resulting in the cleaning effect of the device not working well.

[0034] Working principle: First, the position of the pressing block 203 is adjusted through the threaded connection between the pressing block 203 and the transmission shaft 202, so that the side of the pressing block 203 presses the side brush 204, so that the side brush 204 forms a certain tilt angle, so that it is convenient for the side brush 204 to contact the ground for work. After the side brush 204 is worn, the position of the pressing block 203 can be further adjusted to increase the tilt angle of the side brush 204, thereby increasing the contact between the side brush 204 and the ground. After the side brush 204 is adjusted, the roller brush 3 is installed between the first roller mounting seat 404 and the second roller mounting seat 501, and then the rotating head 506 is rotated by a wrench to make the rotating head 506 drive the threaded rod 505 to rotate, so that the threaded rod 505 moves, and the second support frame 504 is pressed. The roller brush 3 is pushed, so that the second roller mounting seat 501 and the first roller mounting seat 404 clamp and fix the roller brush 3, and the installation of the roller brush 3 is realized. The second roller mounting seat 501 can make the second roller mounting seat 501 squeeze the roller brush 3 more tightly by relying on the threaded connection between the first spring 502 and the rotating connecting block 503. A telescopic guide rod is installed inside the first spring 502, so that the second roller mounting seat 501 can be stressed when rotating. The threaded rod 505 and the shell 101 are threadedly connected to facilitate the operation of the threaded rod 505. At the same time, a rubber pad is arranged at the connection between the threaded rod 505 and the shell 101 to realize self-locking operation. This self-locking function can refer to the self-locking nut. At the same time, the connection between the pressing block 203 and the transmission shaft 202 also adopts the same self-locking structure. When the adjustment and installation of the equipment is completed, the collection box 601 is installed in the equipment. When installing the collection box 601, it is necessary to press the collection box 601 downward with force to connect the collection box 601 with the corresponding block on the shell 101, so as to ensure the stable installation of the collection box 601. After the collection box 601 is stably installed, the contact wheel 705 will be in close contact with the driving wheel 102. In this way, during the movement of the equipment, the contact wheel 705 will drive the collection roller 701 to rotate through the second connecting shaft 704, the transmission belt 703 and the first connecting shaft 702, so that the collection roller 701 can work; The walking path of the device is input on the main board of the device through the intelligent program, and then the driving wheel 102 is turned on to drive the device, so that the device moves. The steering of the device can be controlled by the universal wheel 104, so that the device can move according to the specified route. During the movement, the position is detected by the downward sensor under the housing 101, so that the intelligent program can correct the movement of the device and the device can move according to the specified situation. Then, the first motor 201 is turned on to make the side brush 204 rotate and work, so that the side brush 204 gathers the surrounding garbage to the inside, thereby sweeping the surrounding garbage to the middle part, and then the equipment moves to make the roller brush 3 close to the gathered garbage, at this time, the second motor 401 drives the first roller mounting seat 404 to rotate through the transmission chain 403, so that the first roller mounting seat 404 drives the roller brush 3 to rotate and work; During the rotation of the roller brush 3, the garbage will be thrown into the collection box 601. At this time, the collection roller 701 is also rotating, so that the garbage entering the collection box 601 is thrown onto the shielding plate 603 for collection. The limit block 602 can make the garbage in close contact with the collection roller 701, which is more convenient for the collection roller 701 to throw up. When the collection roller 701 is working, the electrostatic plate 605 will also work to collect dust. The dust can be pulled upward by the fan 606, which is more convenient for the electrostatic plate 605 to adsorb the dust. The electrostatic plate 605 will stop working after working for a period of time, so that the accumulated dust falls into the dust collecting plate 604 for collection. The speed of the fan 606 is relatively slow when working, which only plays a slight traction role and does not directly take out the dust. When the equipment is working, hair will be entangled on the roller brush 3. At this time, the roller brush 3 will pass through the cleaning brush 904 during its rotation, so that the cleaning brush 904 cleans the roller brush 3 to avoid excessive entanglement of hair and affecting the operation of the equipment. If the hair wrapped around the roller brush 3 is too tight, the cleaning brush 904 will be pushed to rotate the cleaning brush 904 around the rotating shaft 903, so that the roller brush 3 can pass through to avoid the roller brush 3 being stuck and causing damage to the equipment. When the cleaning brush 904 is tilted, the connecting telescopic rod 901 will be driven to rotate, so that the connecting telescopic rod 901 will pull the traction rod 804, so that the first piston 803 moves, thereby discharging the gas inside the air pressure box 801 into the annular air pipe 1001, and then through the lower connecting The air receiving pipe 1002 allows gas to enter the outer cylinder 1101, so that the second piston 1104 is pressed down, and the push rod 1106 is extended from the outer cylinder 1101, so that the support leg 1107 supports the device, so that the device is out of contact with the ground and the device does not move, so that the cleaning brush 904 can continue to work until the hair wrapped around the roller brush 3 is cleaned off. The second spring 902 can form traction on the connecting telescopic rod 901 to facilitate the reset of the cleaning brush 904. After the hair is cleaned off, the cleaning brush 904 will no longer swing. At this time, no more air will enter the interior of the outer cylinder 1101, and the air will be slowly discharged from the exhaust hole 1102, so that the second piston 1104 can be reset by the third spring 1105, so that the device continues to work; The first one-way valve 802 is installed at the bottom and rear of the air pressure box 801, and the first one-way valve 802 at the rear is connected to the annular air pipe 1001. The air flow path is that the first one-way valve 802 at the bottom of the air pressure box 801 will rush air into the air pressure box 801, and then the air is squeezed by the first piston 803 to discharge the air from the first one-way valve 802 at the rear of the air pressure box 801 into the annular air pipe 1001, and then enter the outer tube 1101, and then be discharged from the exhaust hole 1102. If the air filled into the outer tube 1101 is excessive, the second one-way valve 1103 will work, thereby The air pressure inside the cylinder 1101 is kept constant at a certain pressure, so you just avoid excessive pressure inside the outer cylinder 1101, which will cause the first piston 803 to encounter greater resistance when squeezing the air, thereby causing greater resistance to the rotation of the cleaning brush 904, making it easy for the cleaning brush 904 to get stuck on the roller brush 3. If the sensor on the device finds that the device has not moved for a long time, it will alarm. At this time, the device may be stuck by the furniture, or the hair wrapped around the roller brush 3 may be too firm and require manual intervention to clean. The hair on the cleaning brush 904 can be cleaned by removing the roller brush 3.
